2005 Hyundai Santa Fe won't start.

Just replaced and engine and have had the battery disconnected for several days. Now there's no spark, then engine will crank and everything comes on but it won't start. Is there a reprogram code for the computer like on the Hondas, or am I needing a sensor replacement?

Thanks for your input and that was the most logical place to start, so I spent two hours changing the crankshaft sensor with a known good one and it didn't help. Is there and active scan tool that will show whether the sensors are working while in use, or while cranking the engine over?Thanks for your input and that was the most logical place to start, so I spent two hours changing the crankshaft sensor with a known good one and it didn't help.

No Start Cranks Ok No Injection Pulse 2002 Hyundai Accent Easy Step By Step ... and car cut off, but would not restart. it sounds like it is starving for fuel. ... hi nice video man . i have no sparkno fuel .u think its the main? it was ...

May be ab bad starter solenoid, or corroded/loose connection at starter, or (ground). Could also be a bad ignition switch. Start from the load; the starter. Test for 12V at starter, OK. Connect short wire from starter and touch sylenoid connection..

best way to see if it is a spark plug wire or bad spark plug connection is lift the hood at night you will be able to see the arc then replace wire, plug or maybe just tighten a loose spark plug. car cranking slowly check battery voltage or battery is getting weak low amperage.

There's a plastic cover on the valve cover, remove small bolt's holding cover, under cover will be two coil pack, and a total of 4 spark plug wire's, remove small bolts to coil pack, will have two bolts to each coil pack, disconnect elec. harness, remove coil pack, spark plugs will be in there.
